高炉卷扬系统是冶金行业炼铁工艺中的重要环节,由于卷扬系统工艺复杂、操作繁琐、连锁保护多,因此卷扬料车运行的安全性、可靠性、稳定性是保障高炉安全生产的重要因素。随着编码器技术的不断成熟,各大钢厂逐步将传统上料系统中的电子接近开关位置感应的机械主令控制方案,改造成为编码器智能电子主令控制系统,改造后的电子主令控制系统运行可靠、响应速度快、调试简便、料车定位 The blast furnace winch system is an important part in the ironmaking process of the metallurgical industry. Because of the complicated process of hoisting system, cumbersome operation and many chain protection, the safety, reliability and stability of the winch operation are to ensure the safe production of the blast furnace Key factor. As the encoder technology continues to mature, the major steel mills gradually transform the mechanical master control scheme of the electronic proximity switch position sensing in the traditional material feeding system into the intelligent electronic master control system of the encoder, and the modified electronic master command Control system is reliable, fast response, easy commissioning, car positioning
